To all ywhom it may concern Be it known thatr I, JOHN A; FRASER, `acitizen of the United States, residing at Nilesz in the county ofBerrien and'State of Michigan, have invented new.

and useful Improvementsv in 'Metal-Forming Machines,

" of which the following is. a specification.

This invention i'relates to a machineqfor forming blank strips of metalstock into commercially useful v forms.

More specifically the illustrative enibodi- It is an ob]ect of my`invention to provide compact convenient easily running driving gear fora machine of .the character dey:

scribed.

Another lobject of my invention is to provide means whereby itispossible to interchange and substitute rolls of va'rvingisizes `andWidths in order to producef'forms of ldifferent shapes in the Vsamemachine.

Another .object of this invention is .to make a comparativelythoroughlyeilicient aId practical machine ri ed. Another "object o` myinvention is to provide a single driving shaft whereby all the formi yrolls `used Ain the'machine are positively riven, this result beingaccomplished referred form of the mvention herein disc shaftsrespectively.

. Another; object of my invention is to ac-l,

tuate all 'of the rolls" by parallel shafts positively connectedtherewith, the connection.

Another olglectA of my invention is to pro' vide flexible aft positivelyconnected With Speci'catlon of Letten Tate-nt.

-one set of the forming rollsin such a fashion as to pernnt` ready.'adjustment of the axes o-'these rolls of -the other eration of themachine. i

A further object of my invention is to provide adjustable bearingstandards for the rollsmade up of a plurality of interlock lng partsconnected by comparatively few bolts and to provide v"ready means forthe ad Justinentv of said standards either bodily one part toward theother, or as concerns portions thereof in which the `roll axes aremounted whereby I obtain a'strong and duyet, one possessing a highcapacity for easy adjustment and capable at the' same time of beinglquickly knocked down or disassembled for` the repair, replacement, etc.,of any of its parts., Another object of my invention to pro vide certainnew easily adjusted :straightentoward or awayfroln the axes set withoutdisturbing the opy ing devices `for the iinishedproduct of the machine.l

Other objects and advantages of my in vention will appeal' as thedescription to follow proceeds. i f In the specified form hereindisclosed, the invention is illustrated in connection with a machineparticularly designed to Amake tubes from blank sheet metal stock bysuc` cessive operations of .a plurality oi. rollers eachof which formsthestock into a certain. definite form. i

The invention, however, also within its scope,

includes they application of other rollers `in a place Vofthe particularset here designedfor the purpose of creating tubes having longitudinalrecesses therein such as lare commonlyused for plate glass settings orany other'form capable of being turned `out by the successive operationof a plu rality of forming rollers.A

Figs. 13 to 20 illustrate the steps in the process of the formation ofthe. tubing by the machine.

The machine comprises a frame having partly in, Section side pieces 1connected intermediately by Webs 2 and tie bolts 3. The side p1eces 1 oneither side' are provided with a cutaway .shelf 4 at the front endthereof, providing e shoulder4 5 for a purpose hereinafter to bedescribed. v

I scart the abutting surfaoes of the parts clamped together ir. thismaehineto provide an interrupted plane Contact which makes possible amuch closer fit and much more secure adjustment of the parts than `itthe reinforces were flat. i .e A

At the rear of the frame I provide a' the space between the Flange' 3Q.and theY shaft 27 being' suitablypacked With'lpaeirqA ingVring'Sgl Thebearingfat the opposite end ofshaft 27 is substantially the same as thatjustdescribed.' Sha-ft 27 carries. a

plurality of worms 38 thereon, each' keyed tween each pairof. adjacentworms',

upon which is mounted the bearing 41' de tachably Secured thereto bymeans of the bolts 42. Onleither vside of the blocks L11 are disks 43and 44 between which Yare mounted the ball. bearing disks 45'.

y structure provides a ball bearing 'thrust gear easing constructed asfollows. The

main portion of the "gear casing; is pro vided ,with two flanges `8 atright angles adapted to be secured upon the top and v rear faces of theframe,` as clearly shown in Fig. 6. Integrally `termed with the frangesS is vaf Worm trough 9, and a. bearing supporting' standard 10,reinforced at inte vais by the Webstl'. having bearings and 13. abovethe trough portion fiend forming ivith the trough portion il, agreasebox Aor the gearing, to be described, is an an gied` cover plate14.

end of the machine frameA is provided with :t

plurality of' key slots 16. 'These .slots are 'adapted to receivecorresponding keys ,7 on the outer base member 5l f the standards Eachladapted to carry the forming rolls.

of these 'base membersfis oi' hollow reinthe shoulder 5 ou the frame andto be. se-y cured thereto-by suit-able bolts. Theinner base member 50 isrigidly fastened in place,' f but the outer member 1s .notuimmovably Atone end of the machine the bearing fastened directly' onfthe shelf/al..The `base members 50 and 51 are provided. with alined T-headslots 53,shown in FigsA and 8,).

Seated upon the.' upper surfaces' of 'the A members 50 andlnreiheintermediate sliding plates each or' which isof identical throughfwhichbolts 57, engaged with nuts 57' in T-slots 53 project to adjustablysecure the sliding plates with respect to the base n'lenibers 50 and 51.i v

The base members 50 and 51 and the slide plates 55each run the length ofthe machine. The slide plates 55 are provided with a plurality of heavyrectangular' ribs 58 in each of which is cut a T-head slot 59.- Seatedupon the upper surfaces of the ribs 58 just described, are the lower,bearing plates 60, each of which is of videntically the same form.These bearing blocks G0 each run the lengthof the machine and are ofreinforced or web construction having a lower web -61 (shown in dottedlines in Fig. 8 and full.

lilies ,in Fig:l 4) which has -slots therein through which penetratebolts 62 coperab ing with nuts i`n T-slots 59 to firmlyA and adjustablyhold the lower' bearing portions 60 -to the slide 4plates 55. Interme1ste the reoeed or webbed portionll 4of. tA e plates 60 are bearingsbosses 63.

lower bearing plates 60are nturned and secured at each end 'by thebolts64. 4 By this construction itV is appa-rent" that the entire supportingstructure `comprising -the -inner and outerfbearing,standards istirmlyfixedas regards relative horizontal displacement. In the louter bearingsstandards are firmly fixed in relation to the inner standards, which -in'turni 'are' secured to shoulder 5..

The lower bearing lates (iO-are-each provided :with a pluralityofrupstanding bosses 65 having threaded sockets which receive the lowerthreadedends Vof a plurality of bolts 66 which 'extendthroughappropriate openings in theupper bearing-blocks 67. and

carry nuts 68 a o ve 'the` b1ocks67. In the sides, of then per bearingblocks 67 are lock bolts 70 -,Whic serve to firmly fix the bearingblocks 67upon-the bolts (i6.

Itwill be seen from the drawings that the low'er bearings 63 in lowerbearing plates 60 are alincd withthe bearings 20 and 12. The lowershafts 45 are squared at their forward ends .to receive the sockets 7lfixed upon square sha-ft 72, bolts 7 3 serving to keep these parte inposition. At 4its opposite end thc shafts 72 carry sockets 74 lxedthereon, which lit over the squared ends of the shafts 75 ournaled .inbearings 63' -inthe lower bearing plates G0.' Upon the shaft-s 75 andbetween the bearing'r plates G0 are mounted rrated along:r the axis ofthe roller shafts to accommodate rolls of different thicknesses.

"It is also desirable to permit the .upper lumi-ing blocks (i7 to movevertlcally'with respect to the lower bearing blocks to accommodal-r4rolls of different diameters. To give The ends of the this adjustment, Iprovide the universal joint drive illustrated in Figs. 1 and 3. The

upper shafts 48m Fig. (i'which are geared to the lower shafts 4:54 aresquared at their ends to receive sockets in the member 77 formingone-half ofthe universal joint constructions 7 8, the other half ofwhich at. 79 are provided with square sockets to receive the squareshafts 80. This structure is duplicated at 'the other end of the squareshaft 80, the outer members 81 of the second universal jointconstruction having square sock- .ets which receive'the squared ends ofthe shafts 82 which are mounted in the alined bearings of the upperbearing blocks 67 and carry the upper forming rolls.

In the operation of the machine, the lnor tor drives the worm shaft 27which in turn drives Aall of the rolls at the same speed, the rolls ofeach pair being. driven in opposite directions. Flat stock is fed tothe'machne in the direction'of the arrows 'shown in Fig.

3. If the rolls are of the ,form shown in l Figs. 13 to 2() the firstset'of rolls I illns- Ytrated in Fig. 14 makes a partial bend in thestock as, illustrated again in Derspectm as indicated by numeral 14 inFig. V13. The second set of rolls II makes a further -bend inthe stockas shown at 15 in Fig. 1B. The

third. fourth, fifth and sixth sets of rolls III to VI graduallyform thestock into a tube as suflicientlyclearlv'illustrated in Figs. -13 to 20.4 t

It is to be understood that many forms and varieties of lforming rollsmay be used" in Athis machine, the specific embodiment of the -inventionhere illustrated disclosing six rollers, this number, however, beingmerely arbitrary and not material to the invention. It is also to beunderstood that the tube can thereafter be provided with a groove toreceive plate glass or the stock may be bent into other forms than intoa tube, all dependingr upon .the number of rolls used and the shapethereof; variation in this respect beingr equally within the scopo o1'the invention.

In front of. the lirst pair of rolls l provide three rods 85, 4twoupper-aud one lower preferably, which are mounted in suitable carriers8G and serve to guide the liat stock to the rolls in preciselyhorizontalplane.

Adjacent the rear end of the machine and suitably fastened to theprojecting en'd of the base member 5l, (see Figs. 9 and 10) I' provldean upetaudingr bracketb havingl an o'sct vertical plate 89 4in which arethreey bearirno;Y slots 8S.

Abolt 92 passes through the angle portion 91 and is threaded vinto theupper end of the vertical plate 8SM 'l`llreaded ou,` bolt 92 arenuts'll'l determlnmg the vertical 'position'of the in embe'r 90..Through a bolt h'ole in platel90 and the slot 88 in themember 89projects the -b'olt 95. Sleeved upon this bolt is bushing.,lr 96. Bolt95 'is provided vwith an enlarged head at one end and .a washer 97 andnut 98 at the other. A roller having a. lcut-away periphery 99 toaceommo-l date-in this v instance a tube, -isV rotatably' mounted upon.this bushing The' construc- ,1`0 tioniof the two lower roll inountingsis sub- .stantially the same; and will be readily understood from thedrawings. By .this construction the-dstance -between lthe axes of"therolls may bevaried, 'or vthe' aperture therebetween vmay be"raised orlowered,

either or both. .The-'lower rolls .10i- Aare similar .to'the upper roll99. IThe purpose'of thisA mechanism is to straighten out the 'tubing asit'fcomes'out of the .mach-ine vand to 2 0' counteract-.any tendency tobend or curl.
